From 2593f07f5c4f736c4b6f5d41a96049801f29e13c Mon Sep 17 00:00:00 2001 From: Richard Moe Gustavsen Date: Mon, 24 Aug 2009 09:01:08 +0200 Subject: Gestures, Mac: remove pan gesture from qabstractscrollarea On Mac there really is no native pan gesture. Instead, this gesture is delivered as mouse wheel events. So adding a pan gesture to qabstractscrollarea means that it will get both wheel and pan events. And both will try to move the viweport. I think that the correct thing to do here is to not apply a pan gesture by default on all scroll areas. --- src/gui/widgets/qabstractscrollarea.cpp | 11 ++++++++--- src/gui/widgets/qabstractscrollarea_p.h | 2 +- 2 files changed, 9 insertions(+), 4 deletions(-) diff --git a/src/gui/widgets/qabstractscrollarea.cpp b/src/gui/widgets/qabstractscrollarea.cpp index 533a56b..28435ef 100644 --- a/src/gui/widgets/qabstractscrollarea.cpp +++ b/src/gui/widgets/qabstractscrollarea.cpp @@ -159,9 +159,9 @@ QT_BEGIN_NAMESPACE QAbstractScrollAreaPrivate::QAbstractScrollAreaPrivate() :hbar(0), vbar(0), vbarpolicy(Qt::ScrollBarAsNeeded), hbarpolicy(Qt::ScrollBarAsNeeded), viewport(0), cornerWidget(0), left(0), top(0), right(0), bottom(0), - xoffset(0), yoffset(0), viewportFilter(0), panGesture(0) + xoffset(0), yoffset(0), viewportFilter(0) #ifdef Q_WS_WIN - , singleFingerPanEnabled(false) + , panGesture(0), singleFingerPanEnabled(false) #endif { } @@ -295,8 +295,10 @@ void QAbstractScrollAreaPrivate::init() q->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding); layoutChildren(); - panGesture = new QPanGesture(q); +#ifdef Q_WS_WIN + panGesture = new QPanGesture(viewport); QObject::connect(panGesture, SIGNAL(triggered()), q, SLOT(_q_gestureTriggered())); +#endif // Q_WS_WIN } #ifdef Q_WS_WIN @@ -547,6 +549,9 @@ void QAbstractScrollArea::setViewport(QWidget *widget) if (isVisible()) d->viewport->show(); QMetaObject::invokeMethod(this, "setupViewport", Q_ARG(QWidget *, widget)); +#ifdef Q_WS_WIN + d->panGesture->setGestureTarget(widget); +#endif delete oldViewport; } } diff --git a/src/gui/widgets/qabstractscrollarea_p.h b/src/gui/widgets/qabstractscrollarea_p.h index 211b7a7..a5acdd1 100644 --- a/src/gui/widgets/qabstractscrollarea_p.h +++ b/src/gui/widgets/qabstractscrollarea_p.h @@ -102,8 +102,8 @@ public: QScopedPointer viewportFilter; virtual void _q_gestureTriggered(); - QPanGesture *panGesture; #ifdef Q_WS_WIN + QPanGesture *panGesture; bool singleFingerPanEnabled; void setSingleFingerPanEnabled(bool on = true); #endif -- cgit v0.12
